{"cve":"CVE-2026-86066","nvd":{"published":"2026-09-25T23:16:54.167","modified":"2026-09-30T01:16:38.087","status":"Deferred","description":"Horilla is an HR and CRM software. Prior to 2.0.0, approve_validate_attendance_request at /attendance/approve-validate-attendance-request/ changes attendance_validated, is_validate_request_approved, approved_by, and related pending-request state through an HTTP GET before calling attendance.save(), so Django does not require CSRF validation for the action. An unauthenticated attacker can cause a logged-in manager with attendance.change_attendance to make a top-level request that carries the manager's SameSite=Lax session cookie, silently approving attendance with the victim's privileges and attributing the approval to the victim in the audit trail. This issue is fixed in version 2.0.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":5.9},"cvss_v3":null,"cwes":["CWE-352"],"references":["https://github.com/horilla/horilla-hr/commit/87a23ecaf2944c15dc5c131f813d2b83fd56eaa0","https://github.com/horilla/horilla-hr/releases/tag/2.0.0","https://github.com/horilla/horilla-hr/security/advisories/GHSA-65vj-5p5g-pv5m","https://github.com/horilla/horilla-hr/security/advisories/GHSA-65vj-5p5g-pv5m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-86066","score":0.0025,"percentile":0.16237,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
